Abstract

The present application belongs to the technical field of glasses, and relates to a pair of smart glasses. The smart glasses comprise a frame, an imaging optical module, an eye-tracking optical module and an waveguide assembly, wherein the frame comprises rims and a connecting part disposed on one side of each rim, a mounting cavity for the mounting of the imaging optical module and the eye-tracking optical module thereon being formed in the connecting part; and the waveguide assembly is embedded in the rims, and comprises a waveguide substrate, and a first coupling-in and coupling-out grating group and a second coupling-in and coupling-out grating group, which are disposed on the waveguide substrate, at least some gratings in the first coupling-in and coupling-out grating group and the second coupling-in and coupling-out grating group being located on the same side of the waveguide substrate, and the gratings located on the same side of the waveguide substrate, namely, a first periodic grating and a second periodic grating, at least partially overlapping to form a composite grating. The smart glasses in the present application can independently couple in or out light rays of corresponding wavebands in the same region on the same side of a waveguide substrate by means of gratings of a composite grating, and thus effectively reduce the absolute area of the gratings, thereby facilitating a lightweight design and improving long-term wearing comfort.
